` j' 'Application ledvMay 13,1925. Serial No. 29,933.

f `My inventionrelates to a'support forconi ductors andwhas particular Vreference to a Y `support foraitrolley wire conductor and a feeder conductor in which the feeder conductor will supply current to the trolley roonductor. Thedevice, however, is adapted to support other conductors `than trolley-conductorsif so desired. ,l l j Y The'object of my invention is to provide a device which' may be securedto" an overhead support andwhich is arranged to be engaged with and disengagedfroma conductor and provide means to supporta-second4 conductor which shally act as a feeder or supply conductor forfcurrent to thetrol-` conductor between the feederconductor and the trolley conductor. f f

It is quitethe practice, especially in mine haulage work, to support the trolley `wire conductor directlyto anoverheadhanger or other support secured to the V'roof of the Y i mine, and to supporta feeder conductor for j the trolley conductor upon brackets secured tothe side wall ofthe mine or to the roof of the mine by means'of hangers 'other than "j j those for securing the trolley conductor to the roof. 'In such practice, connections are made y the feeder conductor andthetrolley conductor.`

My invention resides inthe new andnovel construction, combination and relation of the various parts, hereinafter fully described and disclosed in the accompanying drawing.

In the drawing; l j

Fig. lis a side view of my invention.

Fig. 2 is an end view of Fig. 1. o Fig. 3 is aftransverse sectional view on the kcenter line of Fig.. 1. v

In the preferred form of my construction I employ a member l provided with a' threaded'boss 2 by means of which the de.

vto an ,overheadhanger or a vice is secured support.

Tian oHro `BRASS con I I Merwede a per Iof Clamping im 3 provided with means i to engage the conductor to be supported and the device as shown is arranged to support a trolley wire conductor by the members l entering the grooves along the side of the trolley conductor.' The means of the transverse pintle 5 and the jaws are secured to the pintle 5 by means of the jaws 3 are pivotally secured together by i lugs '6 which are alternately spaced upon the pintle 5. Also secured to the pintle 5is a boss 7 threaded upon the outside to receive a threaded nut 8 which movesvup or down upon the threaded ysurface of the boss 7, depending upon the direction of rotation u ofthe nut 8. The nut 8 is provided with an annular flange 9 which engages the grooves 10 in the jaws 3 and it will be evident that j, `as the nut 8 moves up or down upon-'the Y boss 7 `that the jaws 3 will be' moved into or out* ofengagement with the trolley con# ductor 11. The member l is provided with a groove 12 adapted to receive a feeder conductor 13 and the member 1 is also provided witha ductile tongue 14C arranged to be formed v0r bent into engagement with the i conductor 13 as shown by the' dotted con@` struction in Fig. 3.

The boss 7 is provided with a.v threaded recess 15 and the memberzl is provided with a threaded boss 16 by Ameans of which the boss 7 is secured to the'member'l.` ItA y will be quite evident, however, that 'the bossesv 7 and 16 may be` formed as a single unit. In other words, theboss 16 would be enlarged to the diameter of the boss 7 and will be provided at the lower end with the projecting member 17 secured to the pintle 5 for supporting the jaws 3. The lugs 6 are arranged on either side of the members 17 for securing the parts in pivi otal relation with respectto the pintle 5.

The member 8 is also provided with a lug 18 which is originally formed upright and after theparts are assembled the lug 18 has its upper edge rolled inwardly so that it will engage with the flange 19 and prevent the nut 8 from rising upon the boss 7 as far as it would prior to the lianee 18` being rolled inwardly. i By the use o? the Y flange 18 it is possible to position the pintle 5 in place by moving the member 8 to its extreme height, then placing the pintle 5 in position, together with the jaws 3, then lowering the member 8 and rolling the flange 18 inwardly and this will prevent the member 8 from rising upon the boss 7 a suflicient distance to permit the release of the pintle 5.

The boss 16 connected to the member 1 and also to the boss 7 acts as a conductor or current equalizer between the conductors 1l and 13.

It will be note-d that the axis of the boss 2 cuts the axes at right angles of the conductors 11 and 13, and that the axes of these three members rest in a common plane.

Also, the aXes of the members 11 and 13 are parallel and spaced, but at right angles to the axes of the member 2. Such a construction brings the weight in a central line with respect to the hanger to which the device is supported, therefore, so far as the weight of the conductors is concerned, places no side or bending strains upon lthe parts of the device and such bendlng strains as do occur in the use of the device are due to the conductors taking a curve.

It will be evident to those skilled in the art that I have devised a single mechanism which will support the two conductors from a common hanger, and that there are modilications which may be made from that construction which I have shown and which will fall within the scope of my invention, therefore, I do not wish to be limited other than by my claims.

I claim:

1. A conductor support con'iprising a primary support and a secondary support, the primary support comprising a supporting boss provided with means to secure the support to a hanger, an open groove to receive a feeder conductor, means to be 'formed about the feeder conductor to engage and secure the conductor in place, the secondary support comprising a pair of jaws to engage the conductor to be supported, means to move. the jaws either into or out of engagement with the conductor and means to secure the jaws to the primary support and to conduct current from the feeder conductor to the conductor to be supliorted.

2. A conductor support for two conductors comprising a primary support for one conductor, a secondary support for the other conductor, means electrically connecting the supports together,` the secondary support comprising pivotal means cured'to the connecting means to engage and grip a conductor to be supported, means mounted on the connecting means to move the pivotal means into engagement with the conductor to be supported, and means to connect the support to a hanger.

3. A conductor support comprising a member provided with means to secure the support to a hanger, a pair of jaws to engage and grip a conductor to be supported, means to support a feeder conductor to supply current to the conductor to be supported, bendable means to grip the feeder conductor and means to move the jaws into engagement with the conductor to be supported.

Ll. A conductor support comprisingr a member provided with means to secure the support to a hanger, a pair of jaws to grip a conductor to be supported, hook shaped means to support a feeder conductor in conductve relation to the jaws and means to move the jaws into gripping engagement with the conductor to be supported, the axes of the firsty means, the feeder conductor and the conductor to be supported positioned in a common plane.

5. A conductor. support comprising a member provided with a securingmeans to attach thesupport to a hanger` a pair of jaws to be moved into engagement with a conductor to be suliported, means to receive a 'feeder conductor, means to be bent around the feeder conductor to hold the conductor in position, and means to move the jaws into engagement with th(` conductor, the axes of the conductors being spaced and parallel and at right angles to the axis ol the securing means.
